    摘要: A technique for improving the radiation hardness and hot-electron resistance of a CMOS integrated circuit is described whereby undesirable hydrogen ions may be vented through any holes, such as contact holes, in an overlying passivation layer by applying an elevated temperature and/or electrical bias to the integrated circuit die. The elevated temperature and electrical bias serve to accelerate the process by which hydrogen vents from the die. The elimination of unwanted hydrogen significantly reduces threshold shifts in the CMOS integrated circuit, providing greater radiation hardness and hot-electron resistance.
